MECHANISM FOR EVENING SHEETS OF PAPER N FLY-BOARDS OF PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 316,329, dated April21, 1885.

Application filed October 17, 1883.

To all whom it may concern:

Be it known that we, M. WAGNER BRUSH, of Hyde Park, in the county ofNorfolk and State of Massachusetts, and MIroHELL A.

SALoMoNs, of Boston, in the county of Suffolk and State aforesaid,citizens of the United States, have invented certain Improvements inMechanism for Evening Sheets of Paper on Fly-Boards of Printing-Presses,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, making part of thisspecification, in which- Figure 1 is a perspective View of the fly- I 5board of aprinting-press having our improved sheet-evener appliedthereto. Fig. 2 is a plan of the under side of the same. Fig. 3 is avertical section of the same on the line at w of Fig. 2. Fig. Iis avertical section on the line y y of Fig. 2.

Our invention has for its object to provide a simple and reliable devicefor evenly piling sheets of paper as they are delivered from aprinting-press ontothefly-board; andit consists in the combination, withthe fly board or table of a printing-press, of two or more adjustablecorner pieces or gages adapted to be simultaneously moved diagonally bysuitable mechanismtoward and frorna common center,

0 whereby each sheet as it is deposited by the fly upon the pile isjogged at the corners to cause it to lie evenly with respect to thepreceding sheets, as hereinafter more particular ly set forth; and ourinvention also consists in 5 certain details of construction, ashereinafter set forth and specifically claimed.

In the said, drawings, A represents the fly or delivery board or tableof a printing-press, upon which the printed sheets are deposited 0 bythe fly of the press in the ordinary manner.

At or near each corner of the table A, on the upper surface thereof, isplaced atriangular corner piece or gage, B, composed prefer- 5 ably ofsheet metal, of the form shown, each gage B having two vertical sides, 68, at right angles to each other, and being provided at its bottom,onthe outer side, with alip or flange,

(No model.)

a, having a slot, 12, through which passes a thumb-screw, c, by means ofwhich the corner- 5 gage is adj ustably secured to a bar, D, adapted toslide within a guiding-groove, e, in the upper surface of the table A,and lying flush therewith, or nearly so, as seen in Figs. 3 and 4, this..capability of being adj usted on the bars .55 D enabling the cornerpieces to be placed in the exactposition required to suit the shape orsize of the sheets of paper delivered from the press. The bars D extendfrom points near the corners of the boardA diagonally toward the centerthereof, and are each provided with a series of holes, f, for thereception of the thumb-screw c of the corner-piece B, whereby the lattercan be adjusted to vary its distance from the center of the board A, asmay be required for sheets of paper of different sizes. The inner endsof the barsD are covered and confined in place by a plate, (I, securedto the center of theupper surface of the board A.

From the under side of each bar D projects a pin or bolt, 9, whichpassesthrough a slot, h, in the board A, in line with the groove 6, andcarries at its lower end a friction-roll, t, which fits within a curvedslot or camway, k, in a circular cam-plate, G, secured to the under sideof the board A by means of a screwbolt, Z, around which the cam-plateoscillates.

The cam-plate G is .provided with an arm, m, having at its outer end aslot, 10, in which fits a friction-roll,12-, on a stud projecting from alever, H, fulcrumed at n, and extending out beyond the edge of the boardA, where it is intended to be connected preferably with a strap passingover a pulley on the oscillating flyshaft of the press, whereby it isoperated in one direction against the resistance of aspiral spring, I,by which it is returned to its normal position. If preferred, however,the leverH may be connected with and operated by any other portion ofthe mechanism of the press 0 having the necessary movement at the propertime.

The corner pieces or gages B nearest to the shaft of the fly areprovided with notches or open slots 15, to allow the 'fly-fingers .tode- 5 scend without coming into contact therewith.

The operation is as follows: The partsheing in the position seen inFigs. 1 and 2, with the corner gages -B thrust outward to their fullextent, the sheet -of paper is thrown over by the fly onto the board A,or the pile of sheets previously deposited thereon, and while the air isbeneath the sheet,and before it has had time to settle on the pile, thecorner-gages B are simultaneously advanced diagonally toward the centerof the board with a quick movement by the oscillation of the camplate Gthrough the connections described, which causes the sides 6 8 of thecorner-gages B to strike the corners of the sheet of paper and jog itinto a position exactly over the preceding sheet, on which it is thuscaused to lie evenly, as required, to produce a perfectly even pile ofsheets on the board A. As the fly rises to take another sheet thecam-plate is'oscillated in the opposite direction by the spring I, andthe corner gages B thrust outward to their full extent to enlarge thespace inclosed thereby. in order to prevent any portion of the followingsheets from dropping over the upwardlyprojecting edges of thecorner-gagesB.

We do not confine ourselves to the employment of four corner gages B, asshown, as a single pair of these corner-gages arranged to operatesimultaneously upon opposite diagonal corners of the sheet may be usedin some cases with good results. Neither do we wish to confine ourselvesto the precise construction of the mechanism for producing thesimultaneous diagonal movement of the corner pieces or gages B towardand from a common center upon the upper surface of the board or table A,as it is evident that these movements may be produced by other suitablemechanism without departing from the spirit of our in vention.

e donot claim a table with gages mounted to slide thereon on four sidesof the center, with mechanism, substantially as described, connectedtherewith for automatically and simultaneously moving said gages towardand from the center. Neither do we claim a delivery-table provided withstop-cleats, an adjuster constructed to embrace two sides of the angleof the sheet diagonally opposite said cleats, and means forreciprocating said adjuster diagonally, and such we hereby disclaim.

WVhat we claim as our invention, and desire to secure by Letters Patent,is-

1. The combination, with the fly-board of a printing-press, of theadjustable corner-gages, the diagonally-arranged sliding bars, and theiractuating mechanism, whereby the sheets are adjusted at the corners asthey are successively laid, substantially as specified.

2. The combination, with the diagonallymoving slides havinga series ofapertures near the ends, of the corner-pieces having vertical sides atright angles to each other, and longitudinally-slotted bases, and thepins and nuts whereby the gages may be adjusted in two directions,substantially as and for the purposes specified.

3. The combination, with the fly-board, of the diagonal ly-movingslides, the corn er-pieces having vertical sides, the cam-wheel wherebythe slides are advanced or retracted diagonally, and the lever by whichmotion is imparted to the cam-wheel, substantially as specified.

Witness our hands this 3d day of September, A.-D. 1883.
